I work in marketing and one of my clients had several domains for different campaigns they were running, but we had the sites shut down because it was unhelpful. One of the sites was hacked and started sending spammy links to the main domain, all related to adult content. The site was shut down on 12/6/16 and our main domain recrawled right after, and several times in the weeks after.
Google Search Console is still showing over 4K links from this defunct site. It doesn't show up on Google, it doesn't redirect to the main domain. So why are these links still in Search Console? Is there any way I can get rid of them?
